The wheelset’s 23mm internal width is perfect for running wider tubeless tires at reduced air pressure. That is a vital component of Total System Efficiency™, or TSE™, an approach to speed on ever-changing roads and riding conditions. Specifically, TSE™ focuses on overcoming specific barriers to speed: wind resistance, gravity, rolling resistance, and vibration losses. Zipp’s ABLC™ Sawtooth™ Technology uses an intricate dimpling pattern to improve aero efficiency. Zipp’s use of hookless (straight side) rims in the 404 Firecrest is integral to Making You Faster. With hookless, the transition between the tire and the rim is more seamless and aero. Zipp’s hookless rims have more efficient resin distribution, which means lighter, stronger wheels.\u003c\/p\u003e\n\u003ch6\u003eRear wheel:\u003c\/h6\u003e\n\u003cp\u003eAt 80mm deep, its rim is designed to make you faster in every way. Zipp’s Total System Efficiency design approach, or TSE, infuses the 808 Firecrest with new features, including a huge drop in weight from its previous iteration, well more than 280 grams.\u003c\/p\u003e\n\u003cp\u003eAlso, the wheel is designed with a hookless and tubeless rim profile and 23mm internal width. That’s ideal for running wider tires at lower pressure for reduced rolling resistance and greater cornering grip. In fact, TSE attacks the four primary barriers to speed: Wind Resistance, Gravity, Rolling Resistance, and Vibration Losses. Zipp’s legendary Firecrest rim shape provides high aero efficiency and crosswind stability. Also, Zipp’s ABLC Technology uses a complex dimpling pattern to improve aero efficiency.\u003c\/p\u003e\n\u003cp\u003eWhat’s more, while this wheelset is optimized for tubeless tires, you still have the option to run Tubeless or tubeless ready tires with tubes. The 808 Firecrest with TSE builds on this wheel’s legacy as a go-to wheel fastest or optimized for TT, tri and crit racing. This wheelset is fastest with a 28mm tire. Disc brakes also offer more reliable speed modulation and braking power in all weather conditions. What’s more, in triathlon, running wider tubeless tires at lower pressure makes you faster while also smoothing out the ride so your legs are fresher for the all-important run. \u003c\/p\u003e","brand":"Zipp","offers":[{"title":"XD-R","offer_id":50692662624511,"sku":"210000029054","price":2999.99,"currency_code":"CAD","in_stock":true},{"title":"Shimano","offer_id":50692781048063,"sku":"210000029057","price":2999.9,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0509\/5317\/files\/041799-01_1.jpg?v=1792256353","url":"https:\/\/www.racersportif.com\/products\/zipp-404-808-firecrest-tubeless-disc-b1-hybrid-wheelset","provider":"Racer Sportif","version":"1.0","type":"link"}
